Network science is an interdisciplinary research area that focuses on dynamic processes over networks. Network science problems arise in several domains including sensor and actuator networks, robotics, social networks, and biological systems. The main objectives are to analyze, predict, and control complex behaviors over networks. In this talk I will discuss two problems in network science, namely cyber-physical security and network controllability. Regarding cyber-physical security, I will discuss a control-theoretic framework for cyber-physical systems and attacks, I will present fundamental attack detection limitations, and I will design attack detection monitors. Regarding the problem of controlling complex networks, I will present metrics to quantify network controllability, bounds on the number of control nodes to ensure a certain controllability degree, and a distributed control strategy with performance guarantees.
